Another post has caused me to raise this question instead of hijacking the other post.
How have you separated the hub from the drum? I tried to do this a while back and basically gave up and put them back on the truck. I heated with a propane torch and pounded etc to no avail. What is the secret? ![]()

The front drums are riveted to the hub.

Where? I don't recall seeing any sort of fasteners?

you might need to manually adjust the spring wheel backwards, if it has been awhile a groove can be worn into the drum

You can start with penetrating oil at all the studs and hub and back off the shoes some. Then get a long handled sledge hammer and give it some big time whacks at the out side edge of the drum. The action you make will look like you are pounding it onto the hub. When it lets go it can literally fly off the hub, so don't have anything breakable within 6 feet or so.
and yes, the older front hubs did have the drums rivited to them. Why it would need to be is the real question. GM must have wanted you to be able to stop even though all the studs broke off and the wheel passed you by... if anybody has changed the drum, they would have removed the rivits and never replaced them.

I learned this one the hard way. I actually ripped the face of a front drum trying to get the hub out.
They are definitely rivited. |

I just grind the rivets off, and use a punch to knock them out.

the propane torch is'nt enough get it hot w/ an oxy/acc torch around the studs (make sure to back the brakes off, like mentioned above) and they should come off, don't be afraid of the heat it is your friend

I have not had trouble getting the whole assembly off of the truck. I was trying to separate the hub and the drum so that I could routinely (sp?) check the brakes without pulling the wheel bearings. I will have a look again for the rivets. I don't have oxy- acetyline (sp?) so propane is about as far as I am going to get with heat. I have had good luck with heating with propane over the years so have not spent the money for a better setup.

I have used the hammer method dozens of time. Give it a try. It has taken as many as 20 hits on the worst rusted drums. They have always come off.

You should be able to look at your brake linings through the inspection hole in the drum. If there is no hole there should be an oval area that is embossed. Just knock it out with a punch. You'll have to remove the hub/drum assembly to do this.

While you can get an idea peeking through the hole...it hides way too much to count on what you see. (this IMO anywyas)
